Reaper Prime or Hate?

[Eyeless]

Hello (again) I know I've been starting quite a few discussions on here for comparing weapons, but right now I'm in a bit of a jam and I need some assistance getting out of it. I only have room for one, and can't keep the other. I could craft the Reaper Prime after selling my Hate, or keep the Hate and make the Reaper when I have money for more slots. However, I'd like to know, overall, which scales better against all enemies? Which has more use as a melee weapon? Overall, when it all comes down to it, which has the most potential to be something badass when properly modded and practiced with? Please don't come on here with a simple "I prefer Hate/Reaper Prime" "I like this one because this one is better" "This one is better, other one sucks" etc etc. I want reasoning behind your answers (assuming I get any) Thank you for your time.

Reaper Prime has more DPS (under all circumstances) and staggers on every hit. The latter isn't as useful as other tend to think as the only enemies you want to see staggered are Ancients and Crewmen, and while the latter is being stunned by fire, the first is being stunned by Hate too (although not at 100% chance).
Hate yet deals significantly more damage with a single hit (charge, finisher, etc).

Range and other primary aspects are all the same, so it comes down to how often you use melee and what way. For hit and run-tactics, one-shots and similar, Hate might be the better choice. If you just want to mash charge for maximum damage output from up close, Reaper Prime wins.

I perfected my Hate and am happy with it, as I use it only for the air attacks and one-shots afterwards.
